只是想继续Paolo Moretti和Browserify的精彩回答。如果你正在使用一个编译器(例如babel, typescript)，并且你有单独的文件夹存放源代码和编译过的代码，比如src/和dist/，你可以使用不同的解决方案

node_modules

目录结构如下:

app
  node_modules
    ... // normal npm dependencies for app
  src
    node_modules
      app
        ... // source code
  dist
    node_modules
      app
        ... // transpiled code

然后你可以让Babel等编译SRC目录到dist目录。

符号链接

使用符号链接，我们可以摆脱一些嵌套级别:

app
  node_modules
    ... // normal npm dependencies for app
  src
    node_modules
      app // symlinks to '..'
    ... // source code
  dist
    node_modules
      app // symlinks to '..'
    ... // transpiled code

关于babel——copy-files的警告:babel的——copy-files标志不能很好地处理符号链接。它可能会一直导航到…符号链接和隐性看到无尽的文件。一种变通方法是使用以下目录结构:

app
  node_modules
    app // symlink to '../src'
    ... // normal npm dependencies for app
  src
    ... // source code
  dist
    node_modules
      app // symlinks to '..'
    ... // transpiled code

通过这种方式，src下的代码仍然会有app解析到src，而babel将不再看到符号链接。

在Browserify手册中有一个非常有趣的章节:

avoiding ../../../../../../.. Not everything in an application properly belongs on the public npm and the overhead of setting up a private npm or git repo is still rather large in many cases. Here are some approaches for avoiding the ../../../../../../../ relative paths problem. node_modules People sometimes object to putting application-specific modules into node_modules because it is not obvious how to check in your internal modules without also checking in third-party modules from npm. The answer is quite simple! If you have a .gitignore file that ignores node_modules: node_modules You can just add an exception with ! for each of your internal application modules: node_modules/* !node_modules/foo !node_modules/bar Please note that you can't unignore a subdirectory, if the parent is already ignored. So instead of ignoring node_modules, you have to ignore every directory inside node_modules with the node_modules/* trick, and then you can add your exceptions. Now anywhere in your application you will be able to require('foo') or require('bar') without having a very large and fragile relative path. If you have a lot of modules and want to keep them more separate from the third-party modules installed by npm, you can just put them all under a directory in node_modules such as node_modules/app: node_modules/app/foo node_modules/app/bar Now you will be able to require('app/foo') or require('app/bar') from anywhere in your application. In your .gitignore, just add an exception for node_modules/app: node_modules/* !node_modules/app If your application had transforms configured in package.json, you'll need to create a separate package.json with its own transform field in your node_modules/foo or node_modules/app/foo component directory because transforms don't apply across module boundaries. This will make your modules more robust against configuration changes in your application and it will be easier to independently reuse the packages outside of your application. symlink Another handy trick if you are working on an application where you can make symlinks and don't need to support windows is to symlink a lib/ or app/ folder into node_modules. From the project root, do: ln -s ../lib node_modules/app and now from anywhere in your project you'll be able to require files in lib/ by doing require('app/foo.js') to get lib/foo.js. custom paths You might see some places talk about using the $NODE_PATH environment variable or opts.paths to add directories for node and browserify to look in to find modules. Unlike most other platforms, using a shell-style array of path directories with $NODE_PATH is not as favorable in node compared to making effective use of the node_modules directory. This is because your application is more tightly coupled to a runtime environment configuration so there are more moving parts and your application will only work when your environment is setup correctly. node and browserify both support but discourage the use of $NODE_PATH.

我认为你不需要用你描述的方式来解决这个问题。如果您想在大量文件中更改相同的字符串，请使用sed。在你的例子中，

find . -name "*.js" -exec sed -i 's/\.\.\/\.\.\//\.\.\//g' {} +

/../变成了../

或者，您可以要求配置文件存储包含库路径的变量。如果您将以下文件存储为config.js在示例目录中

var config = {};
config.path = '../../';

在你的例子文件中

myConfiguration = require('./config');
express = require(config.path);

您将能够从一个文件控制每个示例的配置。

这只是个人喜好。

尝试使用asapp:

NPM安装——保存为app

https://www.npmjs.com/package/asapp

var { controller, helper, middleware, route, schema, model, APP, ROOT } = require('asapp')

Controller ('home')改为require('../../controllers/home)

如果你使用ES5语法，你可以使用asapp。对于ES6，你可以使用babel-plugin-module-resolver，使用如下配置文件:

.babelrc

{
  "plugins": [
    ["module-resolver", {
      "root": ["./"],
      "alias": {
        "app": "./app",
        "config": "./app/config",
        "schema": "./app/db/schemas",
        "model": "./app/db/models",
        "controller": "./app/http/controllers",
        "middleware": "./app/http/middleware",
        "route": "./app/http/routes",
        "locale": "./app/locales",
        "log": "./app/logs",
        "library": "./app/utilities/libraries",
        "helper": "./app/utilities/helpers",
        "view": "./app/views"
      }
    }]
  ]
}

我实现这一点的方法是创建“本地链接模块”。

的文件夹结构为例

db ¬ 
    models ¬
        index.js
    migrations
    seed
    config.json

routes ¬
    index.js
    user ¬
        index.js

如果从。/routes/user/index.js我想访问/db/models/index.js我会写

require('../../db/models/index.js')

为了使/db/models/index.js可以从任何地方访问，我在db文件夹中创建了一个名为_module_的文件夹，其中包含一个包。Json和一个main.js文件。

# package.json
{
    "name": "db", <-- change this to what you want your require name to be
    "version": "1.0.0",
    "description": "",
    "author": "",
    "repository": {},
    "main": "main.js"
}

// main.js
module.exports = require('../../db/models/index');

main.js中的路径必须是相对的，就像文件在node_modules中一样

node_modules ¬
    db ¬
        main.js

然后你可以运行npm install ./db/_module_，这将把。/db/_module_中的文件复制到。/node_modules/db中，在应用程序包的依赖项下创建一个条目。json之类的

"db": "file:db/_module_"

您现在可以在任何地方使用此包

const db = require('db');

当你运行npm install时，它会自动安装你的其他模块，工作跨平台(没有符号链接)，并且不需要第三方包。
